Opis:
The article describes quantitative changes in the educational area of the Polish borderland, based on the examples of Nysa, Prudnik, and Głubczyce districts. The demographic data, unfavorable for entire Poland, in the borderland regions are additionally burdened with migration from peripheral communes. It is reflected in the functioning of educational institutions. The analysis of the educational potential of the border areas based on data from the three districts indicates alarming demographic forecasts announcing their depopulation. Breaking that process seems impossible without external support. Thanks to co-financing under efficiently implemented EU projects, and, above all, the work of local leaders, many interesting initiatives were implemented to improve the quality of life in the border areas and their tourist attractiveness, which also gives hope for an economic revival. A positive aspect is that with the decreasing number of students, the number of departments also decreases, which gives hope for a better quality of care, upbringing, and education. However, the data show that reversing the negative trends requires great commitment.

Nowadays, numerous initiatives are being undertaken with the aim to prevent further pollution of air, earth and water. Low temperature district heating (LTDH) offer here an advantage over other heating methods. Implementation of LTDH network into existing buildings have been performed e.g. in Denmark and proved to be feasible without large thermal and in house installation modernisation; however, this must be checked for Polish conditions. The conditions and barriers for such test are discussed here.

The paper presents the analysis of the geo-ecological state of groundwater within an urban territory on the example of Saint Petersburg. The paper considers two key sites, characterized by different levels of contamination of the underground environment (Primorsky and Krasnogvardeisky districts of Saint Petersburg) and provides an assessment of the main natural and man-made sources of the groundwater contamination within the territory of the selected districts. The composition of groundwater was studied in the zones with different pattern of contamination (cemeteries, liquidated landfills, industrial areas, etc.). The negative impact of the man-made sources of contamination on the state of groundwater was determined. The recommendations for arranging hydrogeological groundwater monitoring in metropolitan areas were developed.

This article is an attempt to answer the question: how one selects a neighbourhood to develop an innovation district, using the case of Cracow. This article mainly refers to the issue of the shape of innovation districts, showing how much the morphology of such spaces and their functions can promote or limit the development of innovative enterprises from the Information and Communication Technologies (ICT) industry. It also refers to our research carried out with quantitative and qualitative methods in Poland, using two locations in Cracow as a case study. In this paper, we focus on the significant restrictions which hinder the emergence and development of such districts. We also indicate the potential solutions to these difficulties such as the temporary spaces of events we mapped and which we called ‘totemic spaces’.

Opis:
In the Slovak Republic, the economy of the municipality is governed by the law that considers the indebtedness of the municipality (share of foreign resources on assets) as the main criterion. The aim of this article is to propose an alternative to the legal perspective on the evaluation of municipalities in the Slovak Republic. The article describes the TOPSIS technique as a possibly suitable alternative for the complex evaluation of municipalities’ economy in selected countries. On the sample of 91 municipalities in Presov district, 85 municipalities in Bardejov district and 68 municipalities in Vranov nad Toplou district the TOPSIS method is applied on the basis of 8 previously set criteria. Results of the application are further studied in order to identify correlations between the result and criteria studied as well as the identification of differences (similarities) in the economy of municipalities in reference districts. As results of our analysis can be mentioned imbalance of municipalities’ economy in each district, high variation margin of results achieved or fact that municipalities exhibit the same fixed linking to selected criteria.

The paper presents a proposal for the modernization of a district road No. 1592D relation Polwica-Wierzbno. The aim of the modernization is to improve communication accessibility, increase traffic safety, ride comfort, and to adapt the surface to the current requirements. The technical condition of the road is insufficient, the surface is damaged, roadsides unsuitable and do not have adequate drainage. The degree of damage depends on many different factors. Over the last few years we have been observing significant growth of both transport and construction works. The main factor, influencing the condition of road pavements is high traffic, which results from agriculture development, and the same time more intensive participation of agricultural vehicles in slow-speed traffic, development of heavy good vehicles’ traffic, development of local population and growth of passenger vehicles.

This research aims to analyze the growth rate, and the role of the fisheries sector also to analyze the linkage between the fisheries sector and other sectors in the economic growth rate in the Batubara district. The results of research can be used by local communities and the government as material consideration in determining a policy of management of the economic sector, especially the fisheries sector. This research was carried out from April 2017 to April 2018. The methods utilized are regional superiority analysis, klassentypology analysis, and correlation analysis. The results showed that LQ. LI and SI values of the fisheries sector of Batubara District tend to increase in value from year to year and the fisheries sector itself is in a state of growth. Still, Typology Klassen analysis reveals that the fisheries sector of Batubara district is in the second quadrant. This means that it is advanced but depressed. Moreover, the role of the fisheries sector to other sectors is in the provision of production factors and capital base due to the economy factors built-in to the same space. Herein, the result of correlation analysis of the fisheries sector with other sectors is 0,9. This shows that there is a very strong linkage between the fisheries sector and other sector values in the Batubara District.

District heating networks are key components of efficient heat supply systems for municipal and industrial consumers. The purpose of the research presented in this article was to analyze the thermo-hydraulic parameters of the operation of a transmission main in a district heating network to improve the heat transfer efficiency. Based on a literature review of existing studies, the basic issues of the heat supply process were discussed, and selected methods and tools for simulating district heating networks were characterized. A detailed mathematical description of the phenomena occurring during heat transport in a district heating network pipeline was also presented. Then, analytical calculations and simulations were carried out for the selected district heating system using Termis software. Operational parameters collected in the actual district heating system were used as output data for analytical modeling. Pressure drops, power losses, and heat transfer efficiencies in the main buses at different outdoor temperatures during the heating season were determined. Selected results of the study were included, and possibilities for improving the efficiency of heat transfer in the studied district heating network were indicated.

Opis:
The paper presents the first off-grid system designed to supply electricity to the equipment mounted on components of the district heating network in district heating chambers. The proposed off-grid system is equipped, among other things, with a turbine and a generator intended for electricity production. On-grid power supply is a common way of providing electricity with strictly defined, known and verified operating parameters. For off-grid power supply, however, there are no documented testing results showing such parameters. This paper presents selected results of tests and measurements carried out during the operation of an off-grid supply system powering the equipment installed in a district heating chamber. The values of voltage obtained from a turbine-driven generator are analysed in detail. The analysis results can be used as the basis for further works aiming to optimize the off-grid system of electricity supply to devices installed in district heating chambers.

Opis:
The geothermal potential is challenging to assess, as on the one hand it requires subsurface parametric description; on another – the variable surface influences the potential and geological conditions. In the article, the author presents a novel method for assessing geothermal potential and its environmental impact. The procedure is implemented to evaluate the geothermal potential of the Lublin trough. Geological modelling and GIS analyses are used to determine prospective areas where geothermal water accessibility and sufficient head demand occur in the direct vicinity. Maximal geothermal heat production is estimated, and upon that – possible avoided emissions of air pollutants. The study results indicate that this region's geothermal resources are of low temperature (<50°C), so the only opportunity for exploitation is the direct use of geothermal water in objects or the operation of ultra-low-temperature district heating systems. The main geothermal energy production potential of the Lublin trough is in its northern part, close to the Warszawa trough and nearby main fracture zones. In total, up to 300 GWh of geothermal heat per year might be produced and consumed in the study area if residential and commercial objects could take advantage of ultra-low-temperature district heating system. It would lead to locally significant limitation of air pollutant emissions and decreased fossil fuel consumption.

The goal of this research is to collect and identify the specimens of reptiles that are found in and around Dimapur, Nagaland. As per the research the data on 12 specimens were collected belonging to snakes, lizards and tortoise. The research highlights the diversity and variety of the types of reptiles present in the Nagaland, and also the possibility of discovering many more. We strongly require intensive studies to document reptiles and other biota of the state. Conservation of biodiversity involving local communities would be the best possible option in Nagaland, as the forest area are largely owned by people. Geochelone elegans (Schoepff, 1795), Python molurus (Linnaeus, 1758), Python binittatus (Kuhl, 1820) and Cuora amboinesis (Daudin, 1802), a total of three species reported from the study area were found to be declared threatened by IUCN 3.1.
